A 4-Year-Old with Recurrent Epistaxis and a Unilateral Nasal Mass
A 4-year-old boy is brought to clinic with a 3-month history of recurrent right-sided epistaxis, occurring 3-4 times weekly, mostly at night. Parents report he snores loudly and has had two episodes of blood staining his pillow. He is otherwise well, with no weight loss or fevers. On anterior rhinoscopy, a smooth, pale-pink, fleshy mass fills the right nasal vestibule, and the septum is deviated to the left. The left nasal cavity appears clear. He has no cervical lymphadenopathy, and oropharyngeal examination is normal. A full blood count is normal. The child is uncooperative for flexible nasendoscopy. The nearest CT scanner is 2 hours away, and the family is reluctant to travel.
1. What is the most likely diagnosis, and what is the single most important next step in management? Justify your reasoning.

Most likely diagnosis: Juvenile nasopharyngeal angiofibroma (JNA) - although the classic age is adolescent males, prepubertal cases occur, and the presentation of recurrent unilateral epistaxis with a nasal mass in a young boy must be treated as JNA until excluded.
Key differentials to hold in mind:
- Antrochoanal polyp (usually no significant bleeding)
- Rhinosporidiosis or other infectious granuloma (endemic areas)
- Rhabdomyosarcoma or other sarcoma (rarer, but red flags: rapid growth, pain)
- Hereditary haemorrhagic telangiectasia (usually bilateral, family history)
Single most important next step: Do not biopsy in clinic. The critical judgement point is that a vascular nasal mass in a male child should be imaged before any tissue is taken. The next step is urgent referral to a tertiary paediatric ENT/skull base unit for contrast-enhanced imaging (MRI with MR angiography if available, or CT with contrast) to define the extent, vascular supply, and skull base involvement.
Why this matters:
- Biopsy of a JNA can cause catastrophic haemorrhage.
- Imaging determines whether the lesion extends into the pterygopalatine fossa, sphenoid, or intracranial compartment - this changes staging and surgical planning.
- The 2-hour travel constraint does not justify a clinic biopsy; it justifies an urgent referral and arranging imaging at the tertiary centre in a single trip.
What to tell the family: Explain that the mass needs specialist imaging before any sampling, and that the child should be kept away from nasal trauma in the interim.
2. The MRI confirms a 3 cm JNA confined to the nasal cavity and pterygopalatine fossa with no intracranial extension (Fisch stage II). The family asks about treatment options. Outline the management options and the factors that would push you toward one over another.

Options:
- Endoscopic surgical resection - first-line for Fisch stage I-II disease in experienced hands. Advantages: no facial incision, shorter stay, less blood loss than open approaches.
- Preoperative embolisation (typically 24-48 hours before surgery) - reduces intraoperative blood loss, especially for larger or more vascular tumours. Not usually needed for small stage I lesions, but reasonable for stage II.
- Open approaches (midfacial degloving, lateral rhinotomy, Le Fort I) - reserved for extensive disease, intracranial extension, or where endoscopic access is inadequate.
- Radiotherapy - reserved for unresectable or recurrent disease, or intracranial extension not amenable to surgery; avoided in young patients where possible due to long-term malignancy and growth effects.
- Hormonal therapy (e.g., flutamide) - investigational/adjunct, not standard first-line.
Factors pushing toward one option:
- Tumour extent and skull base involvement - the single biggest determinant.
- Surgeon and institutional expertise - endoscopic resection of JNA has a steep learning curve; outcomes are volume-dependent.
- Vascular supply - feeding vessels from the internal maxillary artery (and sometimes internal carotid) determine embolisation strategy.
- Age and growth potential - favour organ-preserving, minimally morbid approaches.
- Recurrence risk - higher with incomplete resection and with skull base involvement; plan surveillance imaging.
Practical plan for this child: Endoscopic resection at a tertiary centre, with preoperative embolisation if the tumour is judged highly vascular on angiography, and MRI surveillance at 6 and 12 months post-operatively.
3. Two years later, the boy re-presents with recurrent right-sided epistaxis. What is your differential, and how does your prior diagnosis change your investigation strategy?
Read the worked answer
Differential for recurrent epistaxis after JNA resection:
- Tumour recurrence - the most important to exclude; risk is highest in the first 2-3 years and with residual skull base disease.
- Post-surgical anatomical changes - synechiae, crusting, septal perforation, exposed sphenopalatine artery branches.
- Mucosal dryness/atrophy from altered airflow.
- New independent pathology - e.g., a second lesion, or (rarely) radiotherapy-induced changes if RT was used.
- Systemic causes - bleeding disorder, hypertension (less likely in a child).
How prior diagnosis changes strategy:
- Lower threshold for imaging. Any recurrent bleeding after JNA resection warrants contrast-enhanced MRI (and/or CT) to look for recurrence, even if the examination looks like simple crusting.
- Do not assume benign crusting. Examine the nasopharynx and pterygopalatine fossa region carefully; flexible endoscopy in clinic (with gentle restraint or under brief anaesthesia if needed) is essential.
- Review the original imaging to compare and detect subtle recurrence.
- Check for residual disease at the skull base - the commonest site of recurrence.
Plan: Urgent ENT review with flexible nasendoscopy; contrast MRI of the sinuses and skull base; if recurrence is confirmed, re-refer to the tertiary skull base MDT. If imaging is negative, manage as post-surgical mucosal disease with saline irrigation, emollients, and silver nitrate cautery to visible vessels.
